Answer 2

不对
用的是 System.web.ui.webcontrol.treeview

Answer 3

不能自定义xml的，要使用必须用SiteMap那种格式的才能解析，
要不你用c#解析xml来绑定
只能用下面这种节点的格式<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
  <siteMapNode title="Home"  description="">
    <siteMapNode title="Admin" description="">
      <siteMapNode title="发单" description="">
        <siteMapNode url="~/NewBusiness.aspx" title="取件发单"  description="" />
        <siteMapNode url="~/NewSignin.aspx" title="派件发单"  description="" />
        <siteMapNode url="~/Default.aspx" description="" />
      </siteMapNode>
      <siteMapNode title="取件查看" description="">
        <siteMapNode url="~/Business.aspx" title="已上传的有单取件信息"  description="" />
        <siteMapNode url="~/AbnormalBusiness.aspx" title="已上传的取件异常信息"  description="" />
        <siteMapNode url="~/WDBusiness.aspx" title="已上传的无单取件信息"  description="" />
      </siteMapNode>
      <siteMapNode title="派件查看" description="">
        <siteMapNode url="~/Signin.aspx" title="已上传的有单派件签收信息"  description="" />
        <siteMapNode url="~/AbnormalSignin.aspx" title="已上传的有单派件异常信息"  description="" />
        <siteMapNode url="~/WDSignin.aspx" title="已上传的无单派件签收信息"  description="" />
        <siteMapNode url="~/AbnormalWDSignin.aspx" title="已上传的无单派件异常信息"  description="" />
      </siteMapNode>
      <siteMapNode title="统计信息" description="">
        <siteMapNode url="~/Stat.aspx" title="取派员信息" description="" />
      </siteMapNode>
    </siteMapNode>
  </siteMapNode>
</siteMap>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:TreeView ID="TreeView1" Target="mainFrame" ForeColor="#215dc6" NodeIndent="5" runat="server" ShowLines="true" DataSourceID="XmlDataSource1" ExpandDepth="1" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" OnDataBound="TreeView1_DataBound" >

            root.DataMember = "root";
            root.ValueField = "name";
            root.ImageUrlField = "title";
            this.TreeView1.DataBindings.Add(root);

            content.ValueField = "#InnerText";
            content.NavigateUrlField = "url";
            this.TreeView1.DataBindings.Add(content);

Answer 5

//树形菜单绑定
    private void BindTreeView(TreeNodeCollection Nds, int IDStr)
    {
        OleDbConnection sqlConn = DB.CreateConn();        sqlConn.Open();
        OleDbCommand sqlCmd = new OleDbCommand("select * from Tree where ParentNodesID=" + IDStr.ToString() + " order by ShunXu asc,PerNeed asc", sqlConn);
        OleDbDataReader sqlReader = sqlCmd.ExecuteReader();        while(sqlReader.Read())
        {
            if (IDStr == 0)
            {
                TreeNode OrganizationNode = new TreeNode();
                OrganizationNode.Text = " " + sqlReader["NodeTitle"].ToString();
                OrganizationNode.Value = sqlReader["TreeID"].ToString();
                int strId = int.Parse(sqlReader["TreeID"].ToString());
                OrganizationNode.ImageUrl = sqlReader["ImageUrl"].ToString();
                OrganizationNode.SelectAction = TreeNodeSelectAction.Expand;
                OrganizationNode.Expanded = false;
                Nds.Add(OrganizationNode);
                BindTreeView(Nds[Nds.Count - 1].ChildNodes, strId);
            }
            else
            {
                TreeNode OrganizationNode = new TreeNode();
                OrganizationNode.Text = " " + sqlReader["NodeTitle"].ToString();
                OrganizationNode.Value = sqlReader["TreeID"].ToString();
                int strId = int.Parse(sqlReader["TreeID"].ToString());
                OrganizationNode.ImageUrl = sqlReader["ImageUrl"].ToString();
                OrganizationNode.NavigateUrl = sqlReader["LinkUrl"].ToString();
                OrganizationNode.Target = "rform";
                OrganizationNode.Expanded = false;
                Nds.Add(OrganizationNode);
                BindTreeView(Nds[Nds.Count - 1].ChildNodes, strId);
            }
        }
数据库里把节点名称、页面地址、节点图标 、顺序 等存进去就可以了

Answer 6

哎，都忘 了，以前是这么写的：<asp:TreeView ID="TreeView2" runat="server" DataSourceID="XmlDataSource1" ImageSet="BulletedList4">
                    <DataBindings>
                        <asp:TreeNodeBinding DataMember="首页" NavigateUrlField="url" TextField="#Name" />
                        <asp:TreeNodeBinding DataMember="新闻首页" NavigateUrlField="url" TextField="#Name" />
                        <asp:TreeNodeBinding DataMember="添加新闻" NavigateUrlField="url" TextField="#Name" />
                        <asp:TreeNodeBinding DataMember="编辑新闻" NavigateUrlField="url" TextField="#Name" />
                        <asp:TreeNodeBinding DataMember="产品首页" NavigateUrlField="url" TextField="#Name" />
                        <asp:TreeNodeBinding DataMember="添加产品" NavigateUrlField="url" TextField="name" />
                    </DataBindings>
                </asp:TreeView>
                <asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/tree.xml"></asp:XmlDataSource>xml：<?xml version="1.0" encoding="utf-8" ?>
<首页 url="~/Default.aspx">
  <新闻首页 url="~/newsindex.aspx">
    <添加新闻 url="News/add.aspx"/>
    <编辑新闻 url="News/edit.aspx"/>
  </新闻首页>
  <产品首页 url="Product/Default.aspx">
    <添加产品 url="Product/add.aspx" name="添加产品"/>  </产品首页>
  
</首页>

Answer 7

有两种方法，一是直接界面操作，二是在后台用代码实现。
<Root name="root" title="分类">
  <Node Value="aspx/ConsumeClass.aspx" Text="分类"/>
  <Node Value="aspx/ConsumeItem.aspx" Text="明细"/>
  <Node Value="aspx/ConsumeList.aspx" Text="列表"/>
</Root>一：单击treeview上的小三角形，再单击编辑treenode数据绑定，打开treeview databindings 编辑器对话框；datamember 添node;navigateurlfield 填value ;textfield 填 text;
二:
在页面加载事件中写：
//根节点
        TreeNode tnroot = new TreeNode();
        tnroot.Text = "分类";
        tnroot.Value = "Root";
        tnroot.NavigateUrl = "~/你的链接";        //父节点
        TreeNode tnparent = new TreeNode();
        tnparent.Text = "Text";
        tnparent.Value = "Node";
        tnparent.NavigateUrl = "aspx/ConsumeClass.aspx";
        tnroot.ChildNodes.Add(tnparent);
        //子节点以此类推

Answer 8

对了，还忘了一个关键的代码：
treeview1.nodes.add(tnroot);
treeview1.expandall();
